Abstract: An endless heat-generation belt 10 includes a heat-generation layer 11 and a pair of metal electrodes 12 and 12. The heat-generation layer 11 is composed of an electroconductive resin composition and the heat-generation layer 11 can be heated by supplying electricity. The metal electrode 12 is bonded to the heat-generation layer 11 with an electroconductive adhesive 13. The electroconductive adhesive 13 contains an adhesive matrix and an electroconductive filler. The adhesive matrix is a modified silicone resin or an epoxy resin. The heat-generation belt 10 has excellent heat resistance, durability, and resistance stability, and it can be used for a fixing device of an image forming apparatus.
